Device for dispensing cream laden gauze

Abstract

A dispensing device deposits cream onto a strip of gauze by housing a roll of gauze that is unrolled and pulled through a user-fillable reservoir of cream. The amount of cream deposited on the gauze is regulated by applying pressure to various parts of the device. Cream laden gauze is then used in the conventional manner.

Description

FIELD OF THE INVENTION AND BACKGROUND[0001]The present invention relates generally to drug dispensing devices and, more particularly, to a device that produces and dispenses a strip of cream laden gauze from the gauze and cream contained therein.[0002]In the medical field, there are many uses for cream-laden gauze or other cream-laden non-woven permeable materials. These types of combination products are useful in the treatment of skin wounds or abrasions in humans or animals by wrapping the damaged area with a gauze bearing a medicated cream. For example, cream laden gauze wrap for such external use might contain an antibiotic or debridement agent, a hemostatic substance to stop bleeding or other medicinal agents which would be positioned on a wound and subsequently covered with a bandage or dry gauze wrap. Such gauze wraps are frequently used to treat or prevent infections or other adverse events at damaged areas occurring on the extremities, the neck, head, torso or other body lo...

AI Technical Summary

Benefits of technology

[0007]The present inventions are directed to devices that produce and dispense a strip of cream laden gauze. The major structures of the preferred embodiment can include a gauze housing, which retains a roll of gauze; and a cream reservoir, which retains a supply of cream to be deposited on the gauze. The cream reservoir can be filled by removing a plug to expose a threaded or adjustable-entry port, connecting a tube of cream to the threaded or flexible port, squeezing the tube's contents into the reservoir, then replacing the plug. The housing with the roll of gauze can be one end of the device, with the terminal end of the gauze protruding out the other end of the device. As a user pulls on the terminal end of the gauze, gauze is unrolled and travels through a first channel, then through a reservoir of cream, then through a second channel, then exits the device as cream laden gauze. The user is able to regulate the amount of cream deposited on the gauze by applying pressure to the cream reservoir and / or second channel. Cream laden gauze is then used in the conventional manner. The device is preferably disposable, and intended for single usage.

Problems solved by technology

The conventional methods of preparing vaginal gauze packs and other extemporaneously-prepared gauze pack or strips have substantial drawbacks.

For one, it is a messy procedure that requires cleanup afterwards.

Also, it is time consuming for operating room personnel.

Moreover, approximately 15-20% of the cream is wasted, which is substantial considering, for example, that one 45 g of PREMARIN® bears a wholesale cost of about $90.

Most importantly, however, is that cream coverage to the gauze can be non-uniform, thereby potentially lessening the positive effects of the gauze pack.
